If you own a home in Perry County or anywhere across Middle Tennessee long enough, you’ll eventually face the roofing question: when it’s time to replace, do you go with architectural shingles or step up to a standing-seam metal roof?
We install both. Here’s the honest comparison we give homeowners at the kitchen table — no sales pressure, just the trade-offs.
Up-front cost
There’s no way around it: metal costs more to install.
- Architectural (dimensional) shingles typically run the lowest installed cost and cover the vast majority of homes in the region.
- Exposed-fastener metal (the ag-panel look) sits in the middle and is popular on barns, shops, and barndominiums.
- Standing-seam metal is the premium option — concealed fasteners, clean lines, and the longest life.
A metal roof can run roughly two to three times the cost of a shingle roof on the same house. That’s the number that stops a lot of people — until you look at how long each one lasts.
Lifespan: the part that changes the math
This is where metal earns its keep.
- Architectural shingles: about 18–25 years in our climate before they start curling, losing granules, and leaking.
- Standing-seam metal: 40–70 years, often outliving the homeowner who installed it.
Spread the cost over the life of the roof and metal frequently comes out cheaper per year — you’re just paying for more of those years at once. If you plan to sell in five years, that math doesn’t help you. If this is your forever home, it changes everything.
How each holds up to Tennessee weather
Middle Tennessee throws a specific mix at a roof: blistering humid summers, spring hail and wind, and the occasional winter ice.
- Heat: Asphalt absorbs solar heat and bakes; metal reflects it. In a long Tennessee summer, that means cooler attics and a roof that ages more slowly.
- Hail: Both can be damaged by large hail, but metal usually fares better cosmetically and structurally. (Note: very large hail can dent metal — it rarely fails, but it can mark it.)
- Wind: Standing-seam systems with proper clips handle high wind extremely well. Quality architectural shingles are rated for high winds too, as long as they’re installed and sealed correctly.
- Moisture & moss: Metal sheds water fast and gives moss and algae nothing to grab. Shingles on shaded north slopes can grow streaks and moss over time.
The tear-off matters more than people think
Whatever you choose, don’t let anyone shingle over your old roof. A tear-off down to the deck lets us:
- Inspect the decking for soft spots and rot
- Replace damaged sheathing before it’s hidden again
- Install fresh underlayment and proper flashing
Roofing over old material hides problems that come back to bite you — and it voids most manufacturer warranties.
So which should you pick?
A simple way to decide:
- Choose shingles if budget is the priority, or you may move within 10 years. Quality architectural shingles are not a compromise — they’re the right call for a lot of homes.
- Choose standing-seam metal if this is your long-term home, you want the lowest lifetime cost, or you want the look and want to roof once and be done.
Either way, the install is what makes or breaks it. A premium roof installed poorly will fail early; a mid-range roof installed right will go the distance.
